History UI: Ideas & Use Cases

[ScumbagSteve]

My use case is, that I have a lot of different inverters (one Fronius and then a bunch of MicroInverters). The fronius inverter (which has an app) is not aware of the micro inverters and therefore shows 0 consumption during the day. Therefore evcc is the only view where is see the full picture.

I really use the history a lot, but I feel it's a little too detailed to give a good overview.
My proposal would be, to reduce from 5 to 3 graphs.
Summary:

1. How much energy was produced
2. Energy overview
3. Consumption overview

1. Graph: Energy produced

This will probably the most important to a lot. We can keep what we have:

2. Graph: Energy Overview

A unified overview over the consumed energy and where it came from
This is how I would build it:

Battery = Battery return Energy
Grid = Grid Energy
Feedin = ReturnEnergy
Solar = Total energy used - battery Energy - Grid Energy (= the energy that was immediately consumed)

This would 100% replace the "consumption":

As well as grid:

Battery however is only replaced 50%, as we lose the perspective when it was charged to which percentage. I personally don't really care about that, but that's just my opinion. Might be different to others.

Potentially we could leave these existing detailed graphs hidden under an entendable button "show details" / "hide details". This would probably make it more accessible

3. Graph: Electric consumers

We could either keep what we have, or extend the graph also to the consumption of the house (home energy).
I think by also showing the house, the usage of the graph get's a little clearer - as it would show the perspective where the energy went to. Might be either house, heating or car. Only consumers would be considered - as a house battery is more a storage than a consumer, it also makes logical sense to keep leaving it out.

Thanks for the input. The current visualization is deliberately basic. Main goal is to ensure, that the collected data is correct and plausible. See also the note on top of the page:

Work in progress. Visualizations will change. The current focus is verifying that the data is correct. Please report anything implausible.

We already have a lot of ideas on how to make visualization more meaningful, integrated and compact. In optimizer view, we e.g. integrated a lot closer already (consumers under the production envelope). The current state is more or less a "dumb" visualization by data-type.

I dont think we have a good place yet to collect use-cases and different requirements. Let's use this issue as a starting point for that idea collection. I'll convert to a discussion and use this as the canonical location to comment.

Would be great if we could also add household battery soc to a chart, to see how it developed over the day 👍🏻

soc (and tempp) is already being worked on. #30926

Feature request: track solar,battery-share for consumers & loadpoints. See #31334

Maybe we can also implement a button to switch history view to monetary perspective.
We got this in the "charges" view to swap between kWh and €

Especially with a dynamic tariff or module 3 the pure energy itself is not so relevant. The interesting part is, how well the load was moved to cheap times / times with surplus to have lowest cost.

For me it's a very interesting perspective that also can't be covered by any external tool.

Personally, I very much love the openWB time graph on the starting page. It is so great to see whats currently going on in a minutely basis over the course of the last hour. The line graph gives so many insights into the behaviour of the systems and helped me find numerous problems in my setup (e.g. oszillations, toggeling, thresholds, ...). It is also a great help for debugging and gives in depth view of the control behaviour of heat pumps for example, which differs very much from other loads and therefore can require different control strategies.
I'm really happy with evcc but this finely resolved graph is what I miss the most from openWB. Maybe you can integrate a similar "real time" graph into the visualization of evcc, additionally to the more statistical evaluation :-)

Here an example how the graph could look like (please notify me if I must remove it):
